Just came back from Home Depot and the choices confused me.

I understand the coatings are supposed to make the drills harder so they cut better and stay sharp longer
but every mfg seems to have their own buzz words

Cobalt,titanium,black oxide, what do I want for quality?
Yeah I know that some of it is just marketing BS.
Thanks

I chose Milwaukee brand Black oxide but then they are "made in China for Milwaukee" so I don't have real high expectations

EDIT
All around use,fairly heavy use but not really heavy enough to search out a industrial supply house, just trying to find out if anything Home Depo or Lowes carries is a standout or if they are all about the same

I just go to Harbor Freight and buy the small bits in bulk.  When one breaks, I grab a spare...

What material(s) do you plan on drilling?

That would help.

Also, is this like an occasional use or serious shop use?

i like dewalt bits...i think mine are the titanium but i use them for drilling metal. if you are drilling wood just standard bits will be fine.

Why throw good money away on broken junk and possibly ruining your project?  Throwing away a small amount of money is not savings.

MSC Industrial........buy USA made drill bits, Greenfield, bright steel is just fine, nothing fancy.

This.

Drilling pilot holes in wood, any 'ol drill bit will work.  It's the harder materials where you've got to be more careful.

Your material is what decides on the type of bit.

For most uses, just get the "anti-walk" tipped bits.

If you are trying to do many holes in thick metals, tile, plexiglass, etc.   You'll need to worry about the bit a bit more.
